Abstract
In an apparatus for processing an input video signal and generating a special effects video image signal, mapping data representative of the destination upon conversion of each pixel of the input video data is stored in a memory, the mapping data is based upon a write address signal which is added with an offset which becomes larger with the lapse of time. A video image conversion is applied to the input video signal based on the mapping data which is read from the memory in response to a read address signal.
